COTTON-PREPARING MACHINE AND THE LIKE.

Application filed May 13,

To all whom it may concern. I Be it known that I, Josnrrr Moss,- a citizen of the United States, residingat Woonsocket, in the county of Providence, State of Rhode Island, have invented a certain new and useful Improvement in Cotton- Preparing Machines and the like, of which the following is a specification, reference being had therein to the accompanying drawings. I

The invention has relation more particu larly to vertical or upright openers such as are employed in the preparation of cotton or other fibrous material for spinning, al though at least one of the features of the invention is applicable in the case of machines having horizontally disposed cylinders. p

The invention consists in an improved mode of mounting the cylinder of an opener upon its shaft; also, in an improved construction of the shell within which the said cylinder revolves; also, in the combination of stationary wings or bathe-plates with the cylinder shell and external casing of a vertical opener to break up currents of air external to the said shell and within the said casing, and prevent circulation'of air in currents between the shell and easing. The invention is illustrated in the accompanying drawings, in which la'tter,

Fig. 1 shows in vertical section an up right opener to which the features of the invention have been applied.

Figs. 1 and 1 are detail views on a larger scale of certain of the parts at theupper end and lower end, respectively, of the body of the composite or sectional cylinder.

Fig. 2 shows the said opener in horizontal section in the plane indicated. by the dotted b line 2,2, in Fig. 1.

Fig. 3 is' a top view of the shell of Figs. 1. and 2.

F ig. 4- is an elevation of the said shell with one of the wings or baffle-plates in section on line 4, 4, of Fig. 3.

Referring briefly to the main parts of the vertical opener, as the same are shown in the drawings,

At 15, Figs. 1, 1, 1", and 2, is the shaft of the tapering or conical so-called cylinder; at 24, 24, Figs. 1 and 2, are the beater-blades of the said cylinder; at 22, Figs. 1, 2, 3, 4', is the perforated intermediate portion of the 192a Serial No. 5 60,738."

at 27 Figs. 1 and 2, is the adjustment-lever only a few perforasupporting the said step-bearing, 29, Fig. 1, 4

being a stirrup engaged with the outer end of the said lever by means of a cross-pin '30, 28 an adjustment-screw with which the said stirrup is connected,'and 32, Figs; 1 and 2, a hand-wheel by means of which the adjustment-screw -is turned for the purpose of moving the lever 27=to adjust the cylinder vertically to cause the outer-ends of the beater-blades of the cylinder" to occupy positions atthe required distance fromthe inner surface of the shell. The cylinder is shown as provided with driving -means comprising a spiral gear '14, Fig. 1, mounted upon the upper end ofthe cylindershai't 15, and a driver spiral gear 19 mounted upon-a transversely-extending power-driven ackshaftfi; At 17 -is the external or main casing of the machine. The adjustment means and spiral gear drive for the cylinder are not claimed-herein; they form'the subjectmatter of claims in Letters Patent filed Serial N 0. 560,739.

Referring first to the. mode "of mounting the cylinder'upon its shaft :-'-The construc- 2 tion of'the body of the cylinder may vary more or less. In this instance the said body is of built-up composite or sectional character, comprising inits make-up disk-shaped lade-carriers 241, and tions 242, termed separating pulleys, the said short cylinder-secblade-carriers'and separatingpulleys being mounted; in an alternating succession upon the cylindershaft 15,: and tied together in the direction of the-length of the cylinder by means of one or more long tie-rods 243 passing through holes in the blade-carriers and pulleys and furnished" with nuts 244 and washers upon their screw-threaded opposite ends. The cylinder-body is keyed to shaft '15 by means of a long key 245, Figs. 1,1 1 and2. The feature of invention in connec tionwith the cylinder consists'in providing,

for the purpose ofl'ocat'nlg the cylinder-body of the said,, screws hody.- These the shaft, the small ends of the said tapering dowel-pins projecting outward at one" side of the respective collars having burrs 154, 154, which are struck up from the said small ends closely adjacent the peripheral portions of the respective c oll a-ir's;v after the dowel-pins have been driven tightly into pl'acea- The said burrs lock, the dowel-pins against loosening and accidentally working out 01' place. In case it is desired toloosen one of the collars so as toleave the cylinden'hody free to be slid lengthwise of the seen, as in: easel-e- Inova'l the cylinder-'bocly-f-rorn the shaft is required, this may beaccomplished by turn ing the burrs down close to thebody of the tapering securing pin 153 of such collar, and driving the pin out of its holes in the collar and shaft. This will render the collar free to be slipped lengthwise of the shaft, toward the adj acentend of the shaft and oil from such endif required-.

For the purpose of preventing any looseness. and play of the composite or sectional cylinder-body vertically relative to the shaft 15, I combine with the upper collar 151 one 011 more SCrews' 155, the threaded stems of which occupy threaded lioles tapped in the under sidejof the" said eollar; and the heads being" arranged to sir-lake contact jyith the upper end oftl'ie cylinderscrews are turned to cause their heads to bear firmly against the upper end of the cylinder; and then the check nuts 156 with which the screws are protided are tightend up to lock the screws against accidentally turning so as to permit end-play of thecylinder-body upon the cy inder-shaft.

- The described means of holding a beaten cylinder in place upon its shaft is applicable the case of other cylinders of preparing and the like machines; either vertical or hori zont l: c

1 Referring now'to the improved construction of shell I H n p The perforated conical shell 22- is made of th ee (there oif less'if preferred) segmehtal "iee of perforated sheet ama-Figs. a

- and 4'; which are; held together mean of bolts 221, hat are engaged with the out;- ward-ly projecting flanges of ang e-i-rons 222, 222, that are attacliedto the meeting portions of the segments, asby loe's'ingv electrically welded to the exterior surfaces of such portions, or by being bolted or riveted thereto. The said bolts, when tightened up; serve to draw the angle-irons and; the sa d meeting wh ch... i; the segments; hea h n h special feature in this connection is that the joint between one segmental section of the shell and the next is an overlapping joint, such as that shown in Figs. 2 and 5 produced by offsetting the marginal portionof one segmes-tar section so that such marginal portion will overlap the proximate marginal portion of the nextadjoinlng section. The overlap ping is at the inner surface of the shell, and is in the direction of rotation'of the cylinder, so that fibers traveling around or revolving in unison with the cylinder are carried more or less radially disposed. These baffieplates'or wings preferably are attached to the exterior of the shell and project outward therefrom into close proximity to'the exter na-l casing 17 although they may be attached to the inner surface of the external casingl'? and project inwardly therefrom into close proximity to the exterior of the shell.

The outer portions wings 225, wardly in cylinder. or wings are thus inclined there is less tendency to eddyin'g of the moving air around the outer edges of the baflie plates or wings than when they are; simply radial.

What is claimed as-the invention is,-

p 1.- In a preparing machine,- the combination with the cylinder-body, and a supporting and actuating shaft extending lengthwise through the cylinder-body, of collars upon the said shaft at the opposite ends of the cylinder-body serving to locate the cylinder-body in proper position upon the shaft, the shaft and said collars having tapering holes therethrough, and tapering dowel-pins respectively occupying the holes in a collar and one of the holes in the shaft and locked in place therein. y

2; In a preparing machine, the combination with the cylinc er-body, and a supportingand actuating shaft extending lengthwise through the cylinder-body, of collars upon the shaft at opposite ends of the cylinder-body serving to'locate the cylinderbedy in proper positionupon the shaft, said collars and the shaft having tapering holes therethrough, and tapering dowel-p1ns,re' spectively occupying the holes in a collar and one of the holes in a shaft; and having burrs struck up upon their projecting smaller ends which prevent the dowel-pins from working loose. v p 7 In a preparing machine,v the combination with the cylinder-body, and a supportof the baille-plates'jor I find that when the baflie-plates the direction of rotation of the locking the cylinder-body against movement lengthwise of the shaft.

41. In a preparing machine, the combination with the cylinder thereof, ofa shell surrounding the said cylinder, composed; of a plurality of segments combined together by marginal portions thereof overlapping in forming overlapping closed joints.

5. In a preparing machine, the comblnation w th the cylinder thereof, of a shell surrounding the said cylinder. composed of a plurality of segments combined together by means of angle irons attached to their marginal portions and bolts engaging with such angle irons, joints formed by said marginal portions, overlapping in the direction of rotation of the cylinder.

6. In a preparing machine, the combination with the cylinder thereof, of a shell surrounding the said cylinder, composed of a plurality of segments combined together by marginal portions thereof overlapping at the inner surface of the shell in the direction of rotation of the cylinder and forming overlapping closed joints.

7. In a preparing machine, the combina-,

tion with the cylinder thereof, of a shell surrounding the said cylinder, composed of a pluralityof segments combined together by cylinder andwith overlapping closed means of angle irons attached to their marginal portions and bolts engaging with such angle irons, with overlapping closed joints formed by said marginal portions, overlapping at the inner surface direction of rotation of the cylinder.

8. In a vertical opener, the combination with the cylindershell and a casing surrounding said shell, of baffle-plates or wings extending radially or substantially so across the space or interval between thesaid shell and casing for the currents of air outside the shell and within the casing.

9. In a vertical opener, the combination with the cylinder-shell and a casing surr unding said shell, of baffle-plates or wings extending radially or substantially so from of the shell in the purpose of breaking up the shell approximately to the casing for the purpose of breaking up currents of air outside the shell and within the casing.

l0. In a vertical opener, the combination wlththe cylinder-shell and a casing surrounding said shell, of baffle-plates or wings extending radially or substantially so from the shell approximately to the casing for the purpose of breaking up currentsof air out side the shell and within the casing, the said baffle-plates or wings inclining in the direction of rotation of the cylinder.

In testimony whereof I afiix my signature in presence of two witnesses.
